Anna, I'm 6'2" and usually wear a 36" sleeve on a dress shirt. The size large (hoodie version) sleeves are plenty long for me. What helps is the elastic cuff (like the ones on the coats I wore as a kid). I could even have a longer arm and the sleeve would still work- the down part on mine bunches even so slightly. the elastic cuff also keeps the sleeve in place while moving my arms.

So I ordered a medium and ended up selling it because the torso was just too huge. I could have taken 4-6" of circumference out of it and still fit comfortably with a few layers underneath. I'm 5'10", 155 lbs, 30 waist and 37 or 38 suit. I generally wear smalls especially in brands that are more "American" sized but I got the medium after reading reviews that mentioned these run small. I do not feel that was the case for me, and the small fits me well with ample sleeve and torso length. I also picked up a MB Thermawrap jacket in small which fits a bit more snugly; my previous MB pieces were all mediums and had enough room to layer a down vest underneath.

Any want to trade their Small for my Medium?

Wish you had posted this earlier...if you had, I would have not bought my Medium. I went by the fact that the Stoic merino shirt (small) followed the same sizing as the (M) Jacket.

I'm 6' 150 lbs. and it fits me large too. I might keep it anyway, as it closes off very well at the arms and waist, so the extra room would still insulate. I would probably bring this with a fleece for winter hiking...but even with the added bulk it might still be big..

Nevertheless, it's a great item, with good manufacturing quality. Great, lightweight features.

But really--does anyone have a size Small (in any color) that they would be willing to trade for my Medium?

Took my Hadron out for 5 days, high altitude, not much wind, loved it. Got the hooded version, and it was perfect for sleeping with a quilt. Would buy another, just to have a spare, but am spoiled by the initial price.

Usually wear a medium, but the large is fine, perfect in the arms and a little big in the trunk. (5'9", 165 lbs., long arms).
